EGO-350
EGO-350 hydraulic shovel with working equipment
“backhoe” is designed on the basis of EG-350 shovel. Owing to special kinematics
of the working equipment, the shovel can excavate rocks below the floor level.
The availability of lower digging provides effectiveness of backhoe application
when operating on watered faces, at opening of draining trenches and dibholes.
Loading of rocks to transport facilities may be performed both for transport
location below and above the floor level. At customer’s request the main drive
may be diesel or electric.
EGO-350 is electrically driven. The main pumps are of axial piston type,
adjustable with pump capacity 915 cm3. Complete-flow filtration in
hydraulic system involves 6 filters with filtration rating 10 μm and dicharge
capacity 6x1000 l/min. The swing unit – two-stage planetary with forced circular
lubrication. The crawler mounting – multi-support with track roller balancing.
The crawler frame is of welded box structure of high strength and rigidity. The
dipper, boom and stick are made of high-strength steel.
